Abstract
In this paper we present schemes for solving Helmholtz equation. Solve equation by using decomposition complex "wave number" on real and imaginary parts. We concentrate on the use of numerical method based on finite elements. The problem of solving Helmholtz equation becomes one of sparse matrix which solve by using the biconjugate gradient method.
